FLUSH INSERT FOR CONCRETE WORK.

Specification of Letters Patent.

Patented oet. as, 1917.

Application filed April 12, 1917. Serial No. 161,465.

To all whom it may concern:

Be it known that I, DENNIS L. CUMMINGS,

a citizen ofv the United States, residing at Boston, county of Suffolk, State of Massachusetts have invented an Improvement in Flush Inserts for Concrete Work, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to flush inserts for concrete Work such as are used to provide view on the line 1-1, Fig. 2;

Fig. 2 is a sectional view on the line 2'2, Fig. 1.;

Fig. 3 is a perspective view of a device embodying my invention.

My improved insert comprises a box-llke element 1 which may have various shapes provided it is open at one side, as shown at 2. In the illustrated embodiment of the invention the box-like element 1- comprises the? two sides 8 andthe top 4 WhlCh is arcuate. The box is provided with the in shape. laterally-extending flanges 5 at the ends thereof and also with the flanges 6 which extend laterally from the sides 3. Each side 3 is notched, as shown at 7 to receive an anchoring'member 8 which is herein shown as in the form of a rod or heavy wire. This anchoring member 8 is bent into a U-shape and when in operative position the bridge portion 9 thereof extends through the notches 8 and across the open side 2 of the box-like element 1, and the sides or legs 10 thereof extend parallel to the sides 3 of the box-like element and are situated'on the outside thereof. -The extremities 11 and 12 of the legs are bent laterally and preferably in opposite directions.

. In using the device it is placed on the concrete form 13 with the flanges 5 and 6 resting against the form, the insert being placed at the point where some anchorage in the finished concrete structure is desired. When the concrete is poured it flows around the insert and incloses the latter and the legs 10 with their ofi'set portions 11 and 12 be come embedded in the concrete.

When the concrete has set the insert is firmly anchored therein because of the shape of the offset portions 10 and 11 ofthe anchoring member. When the form is removed, a hollow or recess is presented in the face of the concretev due to the presence of the box-like element 1, and this recess has the portion 9 of the anchoring member extending. transversely thereacross. This portion 9 provides a support to which different objects can be secured. It will be noted that in my device the anchoring member serves not only as the support to which attachment may be made, but by reason of its construction it constitutes the means for anchoring the support in the concrete. The device is simple and inexpensive to make and is easily used and is effective in operation.

I claim: 1. An insert for concrete work comprising a box-like element having an open side which is adapted to be placed against the form used for-said concrete'work, the opposite sides of said element having notches therein on their edges, and a U-shaped anchoring member having its bridge portion extending through said notches and across the open side of the box-like element and its legsextending parallel to said sides and provided with means for anchoring said member in the concrete, said member and boxlike element being separable for shipment and adapted for assembling as the device is put into place.

2. An insert for concrete work comprising a box-like element having an open side which is adapted to be placed against the form used for said concrete work, the opposite sides of said element having notches g2 LEIIIIQSQ therein on their edges, and a. Ill-shaped the concrete, said member and boxlike eleanchoring member having its bridge portion ment being separable for shipment and extending through said notches and across adapted for assemblingas the device is put 1(1) the open side of the box-like element and its into place.

5 legs extending parallel to said sides, the In testimony whereof, I have signed my ends of said legs being bent laterally to proname to this specification. Wide means for anchoring said member in DENNIS I1. CUMMINGS.
